To login in to the various social networks tends to be a complicated multiple handshake 32bit task, better suited to a raspberry pi than to an ethernet shield on an arduino. What does everyone else think ?

Excuse me, English is not my mother tongue, for location I meant the act of locating, I made a mistake.If you don't know the distance maybe you cannot estimate any magnitude. You can only say "hey I got a quake and I am here!".Maybe it can be estimated a magnitude based on the signal length.

If you broadcast magnitude, exact time, and location, and others (in other locations) do the same, the epicenter can be located by analyzing 3 or more such reports.
